The present invention relates toa weatherstrip and has particularreference to that type of window weather-strip which is interposedbetween the sliding sashes in the ol sition generally occupied by theparting bead or strip.

One of the particular ob'ects. of the invention is to provide a weater-strip of this type characterized b an improved manner of fasteningthe weat er-strip to the window frame. The present mode of fasteninggreatly simplifies the mounting of the weather-strip, and avoids thelikelihood of deforming the weather-strip in the attaching thereof tothe window frame,

Another objet t of the invention is to provide a weather-strip in whichthe sealing surfaces will have an increased resiliency or spring formaintaining firm sealing contact with the window, for adaptin the stripto different sizes of windows, an for compensating for wear between thesealing suraces.

Another object of the-invention is to provide a weather-strip which willafford the usual line of sealing contact along the side of the sash,and, in addition thereto, will afford a closure or line of sealing alongthe edge of the sash. This sealing contact at the side and at the edgeof the sash greatly increases the effectiveness of the weatherstrip forexcluding the weather. The resiliency of the weather-strip along theside line of sealing contact and along the edge line of sealing contactalso effectively prevents rattling of the window sash in any plane.

In the following description I have described my invention as embodiedin different forms of weather-strip designed primarily for sliding sashwindows. In view of the fact, however, that certain of the essentialfeatures of my invention have wider application to weather-strip andclosure strip than to these particular windows, I have drawn some of t eappended claims to cover a more general application of these essentialfeatures.

In the drawing illustrating the preferred window embodiments:

Fig. 1 is a fragmentary horizontal sectional view throu h theconventional window; having two s iding sashes.

Fig. 2 is a vertical sectional view through the same, takenapproximately on the plane of the line 2-.--2 of Fig. 1.

vFig. 3 is a sectional view on a larger scale of a modified form ofwindow strip,

and

4, 5 and 6 are similar views illustrating other modifications of myinvention.

Referrin to Fig. 1, the side rails of a typical sli ing sash window areindicated at 11-41, and the two sliding sashes are indicated at 1212'.The two sashes 12- 12'v are usually guided in vertical guide channels1-1 which are formed ontheir outer sides by guide strips 15 secured tothe window frame. two sashes are held separated for sliding movement inseparate parallel frames by a parting head or strip which is secured tothe rails '11 of the window frame and which projects slightly betweenthe opposing sides of the sashes. This parting bead or strip is notshown, it being supplanted by the In the usual construction the presentweather-strip. Generally, this part-- mg head or strip is set into achannel shaped groove or recess 17 formed in the side rails of thewindow frame, this groove and its associated parting bead usually beingof a width substantially equal to the width of the space 18 between thetwo sashes. In adapting my improved weather-stri to this conventionalwindow construction utilize the groove -17 for seating a part of theweather-strip. v

The present weather-strip is constructed entirely of a sin lestri ofsheet metal, devoidof any rubTmr surihces or other material likely towear or deteriorate. 'In the particular embodiment shown in Fig. 1 thisstrip of sheet metal is formed with a channel shaped portion 21 oftheflproper size to fit into the groove 17. Extending laterally from oneside of this channel shaped portion is an attaching flange 22 which isadapted to overlie and bear against the surface of the frame rail 11along the side of the groove 17. This attaching flange has a pluralityof holes 23 therein for receiving the shanks of tacks or nails 24:.

From this attaching flange the metalis then doubled back through acurved fold ..to form a second outer flan e 25, which outer flange isspaced slightly From the inner 6 attaching flange 22. This outer flan ealso has a luralit-y of holes 26 therein, a 1 ed with t e holes 23 inthe inner attac flange, the holes 26 being of suflicient size, however,to pass the heads of either the tasks 10 or nails 24. After the channelshaped portion 21 has been seated in the groove 17, these tacks or nailsare centered in the holes 23 and are driven with a punch or othersuitable instrument to prevent deforming 1 the outer flange 25,-engagement ofthe heads of these tacks or .nails with the inner flange 22securely fastening the strip to the win dow frame; the engagement of thechannel shaped portion 21 in the groove 17 assists these nails inholding the strip against 25, subpermitting'it to sprin towards and awayom the flange 22, and this resiliency tends 3 to press this flange 25against thedge of.

the sash, thereby affording a line of sealing contact with the edge ofthe sash, or substantially closing the space which usually existsbetween the edge of thesash and the window frame. The side sealingflange 28 similarly has considerable resiliency tendin to maintain it infirm sealing contact wit the side of the window sash, It will be notedhat the resiliency of this side sealing flange 4 '28 extends through thebowed formation thereof and back through theedge sealing flange 25 tothe point of attachment of the fastening tacks with the attaching flan e22, whereby this side sealing flange has a ditional resiliency tendingto prevent it from assuming an set curvature or position out of contactwit the sash. The resiliency inherent in the edge sealing flange 25 andin the side sealing flange 28 takes up wear, adapts the weather-strip towindows of different dimensions, and avoids all possibility of thesashes sticking. Also, by fastening the weather-strip to the windowframe through the laterally extending attaching flange 22, thedifli'culty of inserting tacks in the depressed channel portion 21is-avoided, and the side sealing flanges 28-28" can be made withrelatively large beaded edges 29 which substantiall close the spacebetween these side sealing an'ges.

Where the weather-strip is only provided with an attaching flange 22on'one side, as shown in Fig. 1, I prefer to use separate strips for the11 per and lower halves of the window and to nvert or reverse thesestrips as shown in Fig. 2. That is to say, when the weather-strips arethus arranged the edge sealing flange 25 for the u per section ofweather-strip will engage behind the edge of the u per window sash whenthis sash 1s in close position and the edge sealing flan e for the lowersection of weather-strip Wlll engage behind the ed of the lower sashwhen this sash is in c osed position. With this arrangement of the twosections of weather-strip the beaded edges 29 of the side sealingflanges 28 will extend in alignment and form a continuousparting beadextending from top to bottom of the window frame. Irrespective of whatposition the sashes 12 and 12 are moved to, they will never pass out ofengagement with their res ective edge sealin anges 25. In the modication shown in 1 3 the weather-strip is formed with a flat portion 32devoid of any channel depression. 21. This type i of weather-strip maybeemployed where the window frame has no groove 17 for the parting bead;or'it may even be employed where the. window frame has such ves. In thisform both sides of the weat er-strip may be provided with attachingflanges 22 and with edge sealing flanges 25. Where edge sealing flangesare provided along. op osite sides ofthe strip a single continuous engthof stri may be extended from top to bottom of the window frame.

In the modification shown in Fig. 4 the beaded edge of one of the sidesealing flanges 28 is formed :with. a laterally extendin flange 33,which contacts with the beade edge of the opposite sealin flange 'comgletely to close the space between these anges.

In the modification illustrated in Fight the side sealing flan s 28-28are provided with straight overapping flanges 34-34 which completelclose the space between these flanges. terminate .suflicie'ntly short ofthe outer sides hese closed flanges 34--34 of the side sealing flangesso as not to restrict the lateral, resiliency of these sealing flan es.1 Fig. 6 illustrates this same arrangement of over-lappin closureflanges in a weather strip having ge sealing flanges 25 on both sidesthereof.
